Case Study: Guosheng Electronic Co. Ltd. achieves paperless, standardized epitaxial wafer production and real-time equipment visibility with Critical Manufacturing MES

Guosheng Electronic Co. Ltd. - Customer Case Study

Guosheng Electronic Co. Ltd. (GS-EPI) is a Nanjing-based OEM of silicon epitaxial wafers producing over 200,000 6” EPI wafers per month. Facing customer demands for a manufacturing execution system (MES) to guarantee uniform epi layers, traceability and quality, GS-EPI moved away from paper and Excel-based recording and selected Critical Manufacturing’s MES to standardize and modernize operations.

Critical Manufacturing implemented the MES incrementally—paperless workflows, workshop visualization, a single production data source, WIP traceability, preventive maintenance and reporting—going live in April 2015. The system delivered automated data collection, standardized production flows, real-time equipment status on one screen, error-free recipe selection and complete traceability, reducing manual work and improving efficiency to support GS-EPI’s growing volumes.
